My 1999 GL1500SE is easy to get into neutral BUT very hard to get the neutral light to come on. I know the routine is clean the reverse switch and sides stand switch which I've done with no change. Reverse works good and side stand checks out and bike starts with clutch in .The best way to get the neutral light to come on is to go from second to neutral. If you go from first to neutral the bike goes to neutral but the green light simply flashes on and off even though thebike itself is in neutral. The problem is worse when it is cold and improved somewhat when the bike is warmed up . Although annoying I simply put up with this however now my bike has failed a safety inspection due to the difficulty of getting the Neutral light to come on . Anybody got any ideas ?

Same answer here too..My neutral lamp only comes on from first to neutral...It seldom goes on from second to neutral.Unfortunately I did not fix this by tearing apart the switch and resurfacing the contacts...I'm actually quite good at this I did find the "landing pad " for neutral was very small..and the switch was not intended to be disassembled...I can only assume that the switch control link needed to be positioned exactly on the mark for it to work and the mechanical linkage that turned it was just a bit sloppy..All my work on the switch did not improve its operation at all and I have not gone back to do any more to it.Soooooo....just be aware that just throwing in a new switch may not fix it....Better check the coupling too...As a mater of fact...a loose coupler fork may be the only problem...Either way,I do suggest a "dry fit " test of the switch and cover before you gasket it and button it up...Please test and verify a few times...You know...do as I say... not as I (didn't) do.

Actually the landing pad for neutral is reasonable but the landing pad for the neutral light is tiny and touchy .the bulb is good so I'll check the wiring . I need to get this solved for the safety inspection so will have to tear into it . I've done timing belts and throttle cables so this will be new territory . I have the shop manual . How big a job is it ?

The landing pad I refer to is the brass button inside the gear selector switch that the ground wiper makes contact with to ground the neutral lamp circuit....It takes a while...drain the oil and radiator...remove the front cover of the engine...The switch is inside there..This pix may help...
